Levi Neuwirth f7267cd720 T M4.5 L1: cross-file nav foundations — per-buffer file_path, jump ring, x-file go-to-def
Lays the groundwork for WorkspaceEdit/rename (L2+) by making
navigation cross-file-correct.

- Relocate file_path/file_meta from the EditorCore global onto
  Buffer itself, so each buffer keeps its own filesystem identity
  across cross-file navigation. Accessors + registry/editor/lua/
  semantic_render call sites migrated; zero behavioural change for
  single-file flows.
- uri->path: project_index::uri_to_path made pub; pmacs.lsp.path_for_uri.
- find-or-open: BufferRegistry::find_by_path + pmacs.buffer.find_or_open
  dedups an already-open file instead of spawning a duplicate buffer
  (SP-4 Gap A).
- Bounded jump ring on EditorCore (cap 64, oldest-evict, stale-buffer
  skip): push_jump/jump_back + pmacs.editor.* bindings + lsp.jump-back
  command bound to M-,.
- pmacs.lsp.go_to_definition cross-file branch: decode URI ->
  push_jump -> find_or_open -> reposition, with a failure path that
  unwinds the pushed origin. ensure_server now passes cfg.env through.

Tests: 5 jump-ring unit tests; m4_12_cross_file_go_to_definition_and_
jump_back end-to-end via a new `defenv` fake-LSP mode. All gates green
(lib 1262/0, m4 67/0, m8_1/m8_9/m8_10, m9_1, m11_5 --features crdt 2/0).
